Topband: RCS-4 Noise found! by N0AH

Gosh, I really hate to see people think there is something wrong 
with sending voltages down a feeder to control relays. 

I'd like to personally see a bad RCS-4 unit, in case there is 
something wrong with current production. If someone can send one 
here, I'll see that they get reimbursed. There was a change made 
recently, using an external transformer. I hope that isn't causing a 
problem.   

ALL of my beverages have AC running down the cables, and 
always have. Many systems use that method. It is absolutely 
incorrect to assume it causes any problem with a proper feedline.

For example, my Beverages in Cleveland Ohio used 48 volts 60 Hz 
AC piped down the coax along with tone signals. My current 
Beverages 2500 feet away use voltage down the cables, just like 
the RCS-4. So do my receiving verticals. 

One thing to be aware of, bad connections, open shields, or water 
in the fittings will cause a lot of noise in a hurry when there is AC 
or DC on the feedline. 

It is an absolute must that feedlines have dry fittings, and good 
connections are made, when control voltages are piped down the 
cable. 99% of the problems in the past turned out to be in the 
feedlines.
